Bradford (), also known as the City of Bradford, is a metropolitan borough in West Yorkshire, England. It is named after its largest settlement, Bradford, but covers a larger area which includes the towns and villages of Keighley, Shipley, Bingley, Ilkley, Haworth, Silsden, Queensbury, Thornton and Denholme. Bradford has a population of 528,155, making it the fourth-most populous metropolitan district and the ninth-most populous local authority district in England. It forms part of the West Yorkshire Urban Area conurbation which in 2011 had a population of 1,777,934, and the city is part of the Leeds-Bradford Larger Urban Zone (LUZ), which, with a population of 2,393,300, is the fourth largest in the United Kingdom after London, Birmingham and Manchester.
The city is situated on the edge of the Pennines, and is bounded to the east by the City of Leeds, the south by the Metropolitan Borough of Kirklees and the south west by the Metropolitan Borough of Calderdale. The Pendle borough of Lancashire lies to the west whilst the unitary authority of North Yorkshire lie to the north west and north east of the city. Bradford is the 4th largest metropolitan district in the country, and the contiguous urban area to the north which includes the towns of Shipley and Bingley is heavily populated. The spa town of Ilkley lies further north, whilst the town of Keighley lies to the west. Roughly two thirds of the district is rural, with an environment varying from moorlands in the north and west, to valleys and floodplains formed by the river systems that flow throughout the district. More than half of Bradford's land is green open space, stretching over part of the Airedale and Wharfedale Valleys, across the hills and the Pennine moorland between. The Yorkshire Dales and the Peak District are both in close proximity.
